Structured Packing Distillation Technology and Plant   Sheets Combined Corrugated Structured Packing  (Zupak) Each periodic ripple of the Zupak is composed of more than four intermittent planar graphic sheets located on four planes. The lateral projection shape is two interlaced corrugated lines. The uniform parallelogram channel on the filler has completely replaced the circular holes on the regular structured packing. It can not only save 8.5% of the material, but also increase the specific surface area of the corresponding quantity. The packing has the advantages of low pressure, large flux, good transversal air permeability and high separation ability. It can be widely used in the industrial fields of distillation, absorption, extraction, heat exchange, washing and so on. Compared to corresponding Mellapak packing, Zupak has advantages as follows: The specific area increases by around 10%; The porosity opening rate increases by 30-40%; The separation efficiency increa...

Air Separation Packing Air Separation Unit (ASU) Packing Air Separation Packing Technology Distillation Technology and Plant We agent the ASU packing of Tianjin Univtech Co., Ltd., who was honored as the technical center of national chemical packing tower and internal fitting in 1990, and whose “ High Efficiency Packing Column with New Type Column Internals” have been listed as the key marketing project among China’s “the Eighth Five-Year Plan” and “the Ninth Five-Year Plan” technology achievements. Product Type Conventional ASU Packing Its plain edge design has improved the gas-liquid flow at the interface of two adjacent packing tray to decrease local resistance, avoid early flooding and enlarge the equipment flexibility range. High Throughout Packing Especially applicable in large scale ASU. Its special edge curve transition structure has good division effect to reduce the liquid accumulation among packing trays, increase the packing flooding point and the opera...

Technology Introduction of Formaldehyde Plant Formaldehyde Plant SL TEC has close to ten years experience in formaldehyde production technology based on silver contact process(or silver catalyzed process). A lower methanol consumption, higher formalin product concentration, high export steam capacity and ease of operation are our features, which makes it the best technical and economically viable solution. Every unit operation incl. methanol evaporation, catalytic reaction, absorption, off-gas treatment has optional design to at best satisfy the customer’s needs. We provide one-stop package solutions from the formaldehyde plant  design, manufacture, erection, commissioning, startup to training, with the production capacity of 6,000TPA – 120,000TPA and the formaldehyde product concentration varying from 37-55%. And according to the customer’s different needs, there are totally 7 (seven) optional processes as follows: 1) Traditional Bubble Evaporator + Absorber with 3 (thr...

Formic acid production technology Agent Technology and Plants   Technical Features: Methanol Carbonylation Synthesis of Formic Acid from Methyl Formate Formic acid is an important chemical raw material for a wide range of uses. After the successful development and construction of methanol carbonylation of methyl formate 30,000 tons / year industrial plant, the company successfully developed methanol carbonylation of methyl formate , With a short process, easy to obtain raw materials, investment in the province, no waste emissions, the advantages of low production costs. Performance: Brief description of the process: CO and methanol mixed with the catalyst after a certain pressure and temperature of the carbonylation reaction to form methyl formate, with methanol to absorb the tail gas entrainment of methyl formate, methanol, condensate back to the reactor. The crude product containing methyl formate is rectified in a pressurized distillation column, and the meth...

Concentrated Recycling Technology of Formaldehyde Proprietary Technology and Plants Technical Features: In the production of paraformaldehyde and polyoxymethylene, high concentrations of formaldehyde are required as raw materials. But the normal formaldehyde production, whether it is silver or iron molybdenum, the product concentration is not more than 55%. So the need for raw materials for dehydration dehydration enrichment, and enrichment process will produce dilute formaldehyde. Dioformaldehyde is usually used to produce downstream products (such as urotropine, methylal, etc.) that are not required for formaldehyde feedstock concentrations and enrichment and recycling. Commonly used dilute formaldehyde concentration recovery technology there are two, respectively, decompression flash separation process and pressurized distillation enrichment process. The former in the concentration process will once again produce about 8% of the dilute formaldehyde; the latter can be recove...
